Very useful

This web has come so much handy when it comes to preparing for the SAS Clinical Trials Programmer certification. 
I have created an account here and paid for the premium exam within 6 hours, I got access to the practice tool and I have started practicing, this has helped me a lot as I have prepared for the exam in 6 days that to working days. and next week monday, I just juped in to taking the certification exam.. Bang on, I have cleared the same with good marks.
